I have purchased the ticket for a total of 55,000 united miles and $197 per passenger:
5/24 LH 401 JFK- FRA 4:00pm-525am
5/25 LH 4672 FRA -AMS 9:25am -10:25am
In Amsterdam 5 nights with family
5/30 LX 725 AMS-ZRH 9:45am- 11:10am
1 night at the PH Zurich using 18k HGP
5/31 LX 656 ZRH-CDG 4:40 PM - 5:55pm

6/1 AC 881 CDG-YYZ 11:20-1:10pm
6/1 AC 722 YYZ-LGA 6:15pm-7:25pm
Please note that I managed to get 2 free stop-overs on this ticket. (The stay in Zurich is 30 hours long). Not really sure how that got past them :-). United did charge an additional $25 per pp for booking on the phone. (A ticket with Star Alliance partners is not bookable online.)
